DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example 1

[0020] See also Figure 1This embodiment introduces an automatic workpiece flipping and feeding device, which aims to improve the automation and intelligence of tobacco packaging materials, so as to realize the automatic feeding, caching, feeding and cutting of workpieces. The device is composed of a flipping channel 21, an acceleration channel 22, a cutter 23 and a feeding channel 24, realizing a fully automated process from workpiece entry, acceleration, cutting to final feeding. The flipping channel 21 is provided with a conveying channel 35 for transmitting workpieces. When working normally, the workpiece enters from the entrance of the conveying channel 35 on the right side, is accelerated by the acceleration channel 22, and is sent to the cutter 23 from the exit of the conveying channel 35 for cutting. Finally, the cut workpiece is then pushed into the feeding channel 24.

[0021] See also Figure 2 and Figure 4 The flip channel 21 includes a cylinder 51 and a gas support 31. One end of the cylinder 51 is fixed to the lower base 52 through a first rotating shaft 53, and the cylinder extension rod connected to the other end of the cylinder 51 is rotatably connected to the channel connecting plate 57 through a second rotating shaft 54. The channel connecting plate 57 is fixedly connected to the conveying channel 35, and the conveying channel 35 is connected to the upper base 55 through a fixed shaft 56; Further, one end of the gas support 31 is connected to the lower base mounting plate 34 through the first rotating shaft 32, and the other end is fixed to the conveying channel 35 through the second rotating shaft 33; When the cylinder 51 is extended, one end thereof is fixed to the lower base 52 via the first rotating shaft 53, and the other end is rotationally connected to the channel connecting plate 57 via the cylinder extension rod, driving the channel connecting plate 57 to rotate around the fixed shaft 56, thereby driving the flip channel 21 to flip upward. This action allows the channel to flip to make room when not in use or in need of maintenance, without affecting the normal operation of other parts.

[0022] In summary, the device not only improves the flexibility of the equipment and the convenience of maintenance, but also ensures that manual feeding will not be hindered when the equipment is repaired or not in use, thereby improving production efficiency and operational safety. In addition, the flipping action of the flipping channel 21 can be performed when the cutting machine 23 stops working without affecting the automatic operation of the feeding channel 24, thereby realizing independent control between channels. The application of this automatic flipping and feeding device makes the processing of tobacco packaging materials more efficient and accurate, while reducing manual intervention, reducing labor intensity, and improving the overall level of production automation. Example 2

[0023] See also Figure 3, in order to achieve efficient and accurate processing of workpieces, the level of production automation is significantly improved. The operation of the flip channel 21 is controlled by a motor 41 and a driving shaft 43. One end of the motor 41 is connected to the first synchronous belt 42. The motor 41 drives the driving shaft 43 to rotate through the first synchronous belt 42. One end of the driving shaft 43 is connected to multiple synchronous pulleys 44. The multiple synchronous pulleys 44 are meshed with the corresponding multiple second synchronous belts 45. In the embodiment of the present invention, the driving shaft 43 transmits power to the three synchronous pulleys 44 through a hard connection (which can be a key, a pin or other mechanical connection method). The synchronous pulley 44 transmits power to the three second synchronous belts 45 by meshing with the teeth of the second synchronous belt 45, so that the second synchronous belt 45 rotates. When the second synchronous belt 45 rotates, it will drive the driven shaft 46, the guide wheel 47 and the tension wheel 48 to rotate, thereby ensuring the smooth operation of the flip channel 21.

[0024] Furthermore, the tensioning wheel 48 independently adjusts the tension of the second synchronous belt 45 by rotating the swing arm 49, and multiple tensioning wheels 48 are installed independently of each other, so as to achieve the purpose of fine adjustment of the tension of each synchronous belt, and the tensioning wheel 48 can adapt to different operating conditions and improve the stability and reliability of the system.

[0025] In order to ensure that the flip channel 21 can be firmly positioned after the cylinder 51 and the gas strut 31 are fully extended, the device is specially provided with a pin hole 37, through which the flip channel 21 is fixed by inserting the pin 36, to prevent the channel from accidentally falling due to failure of the cylinder 31 and the gas strut 31, thereby enhancing the safety of the device.

[0026] See also Figure 5 The acceleration channel 22 is equipped with an acceleration belt 81, so that the workpiece can be quickly fed into the cutting machine 23 for cutting, thereby improving production efficiency. The side push electric cylinder 82 installed in the cutting machine 23 is responsible for driving the cut workpiece to move, and the feeding channel 24 includes a feeding channel waiting position 84, a feeding electric cylinder 85 and a feeding channel belt 83. The side push electric cylinder 82 feeds the cut workpiece into the feeding channel waiting position 84 for temporary storage, and then the feeding electric cylinder 85 pushes the temporarily stored workpiece into the feeding channel belt 83, and then feeds it into the feeding port of the main machine through the feeding channel belt 83, thereby realizing seamless connection of the workpiece from cutting to feeding.

[0027] See also Figure 6 and Figure 7 A foot 87 is provided under the feed channel 24, and the foot 87 is connected to the feed channel 24 through a main shaft 86, providing additional stability.

[0028] It should be noted that, except for the foot 87 under the main shaft 86, the rest of the footings of the entire device are roller footings. When the device needs to be moved, the brake can be released and the device can be rotated around the main shaft 86 to avoid the space behind the device.

[0029] See also Figure 8 A material blocking mechanism 93 is also installed at the joint of the acceleration channel 22 and the flip channel 21. Baffles 94 are provided on both sides of the material blocking mechanism 93 to control the flow of workpieces, ensure that the workpieces enter the cutting machine 23 in an orderly manner, prevent the workpieces from piling up or misalignment, and further improve the accuracy and efficiency of cutting.

[0030] To sum up, the workpiece automatic flipping and loading device of this embodiment not only improves the degree of automation of workpiece processing, but also ensures the safety of operation and high efficiency of production, and is suitable for various industrial automation scenarios such as tobacco packaging materials. Example 3

[0031] See also Fig. 9 The present embodiment describes an automated workpiece flipping and loading method, which achieves efficient and orderly loading and cutting of workpieces by precisely controlling the coordinated action of the flipping channel 21 and the acceleration channel 22.

[0032] When the cutting machine 23 needs material, the flip channel 21 is operated to retreat a preset distance to reduce the pressure of the workpiece on the baffle, and then the material blocking mechanism 93 is opened to allow the workpiece to pass smoothly. In this process, the flip channel 21 and the acceleration channel 22 rotate synchronously, and the flip channel 21 starts to push the workpiece forward, ensuring the continuous supply of the workpiece.

[0033] When the workpiece contacts the acceleration belt 81, the workpiece is accelerated on the acceleration channel 22, forming a speed difference with the workpiece that has not contacted the acceleration channel 22. This speed difference naturally forms intervals between the workpieces, so that they enter the cutting machine 23 in an orderly manner, avoiding the accumulation and confusion of the workpieces. This interval control not only improves the accuracy of cutting, but also reduces possible machine failures and material waste.

[0034] After the last workpiece passes through the stopper mechanism 93, the stopper mechanism 93 closes and continues to accelerate the workpiece into the cutting machine 23 for cutting. This cycle continues until the workpiece moving forward on the turning channel 21 again hits the stopper mechanism 93, thus completing a feeding cycle. This method ensures the continuous supply of workpieces and the high efficiency of the cutting process, and reduces the idle time of the machine.

[0035] Finally, the cut workpiece is then pushed into the feeding channel 24, and the cut workpiece is fed into the main machine through the feeding channel 24, completing the entire automated process from loading to final loading of the workpiece. The entire loading method improves production efficiency, reduces labor costs, and ensures consistency and reliability in workpiece processing, which is of great significance for improving the overall performance of the production line and reducing operating errors.

[0036] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which all fall within the protection of the present invention.
